Goeppertia latifolia
Goeppertia latifolia (Broad-leaf Calathea) Care Guide
Featured photogoeppertia-latifolia.jpgGoeppertia latifolia, sold under the common name Broad-leaf Calathea, is a tropical Marantaceae understorey plant kept indoors for its patterned foliage. True to its species name, this plant has unusually broad, paddle-shaped leaves that can exceed 30 cm across at maturity. Like most members of the genus, it prefers bright filtered light, evenly moist soil, and humidity above 60 percent — the leaves curl and brown at the edges when air is too dry or watering is uneven.

Overview
Goeppertia latifolia was reclassified from Calathea into Goeppertia in 2012 along with most ornamental species in the genus. True to its species name, this plant has unusually broad, paddle-shaped leaves that can exceed 30 cm across at maturity. The leaves fold upward at night — the prayer-plant nyctinasty that Marantaceae is named for.
Care Priorities
- Bright filtered light, never direct midday sun.
- Evenly moist soil — neither soggy nor dry.
- Humidity above 60 percent; group with other tropicals or use a pebble tray.
- Water with rainwater or distilled water to avoid leaf-edge burn.
- Divide every two to three years to refresh growth.
Common Problems
Crispy leaf edges almost always trace back to dry air, hard water, or inconsistent watering. Curled leaves point at thirst or low humidity. Yellow lower leaves with a sour-smelling pot mean root rot — repot into fresh free-draining mix.

Frequently asked questions
How much space does Goeppertia latifolia need?
Mature plants spread 60 to 90 cm wide and need a pot at least 25 cm in diameter once established. Give it floor space rather than a tabletop spot.
Why are my Goeppertia leaves browning at the edges?
Browning edges are usually caused by tap water (chlorine and fluoride accumulate in the leaf margins), low humidity, or dry root balls between waterings. Switch to rainwater or distilled water and aim for at least 60 percent humidity.
Should I mist this plant?
Misting raises humidity briefly but is not a substitute for ambient humidity above 60 percent. A humidifier or grouping with other plants is more effective and avoids fungal problems on the leaves.
